20G 22G MDR CE Disposable Radiofrequency Needle Medical RF Needle

20G 22G MDR CE Disposable Radiofrequency Needle Medical RF Needle

Reliable energy delivery for C-arm and fluoroscopy-guided radiofrequency ablation.

Designed for interventional pain management procedures including facet joint denervation, medial branch neurotomy, and peripheral nerve ablation.

What is a Radiofrequency (RF) Needle?

A radiofrequency (RF) needle is a sterile disposable electrode used in minimally invasive RF ablation procedures. It delivers controlled RF energy from a generator to targeted tissue, creating thermal lesions for pain management, nerve ablation, or soft tissue coagulation.

The needle is designed to work as a precise energy delivery interface between the RF generator and human tissue, ensuring controlled lesion formation with minimal collateral damage.

How RF Needle Works in Tissue

When connected to a radiofrequency generator, the RF needle delivers alternating current into biological tissue. The electrical resistance of the tissue converts this energy into localized heat, forming a controlled lesion at the target nerve or tissue site.

This process allows clinicians to interrupt pain signal transmission while minimizing damage to surrounding healthy structures.

• Stable and consistent RF energy conduction
• Optimized bevel tip for controlled needle placement
• Medical-grade insulation for safety during ablation
• Compatible with major RF lesion generators

Our RF cannula is widely used in minimally invasive pain treatment procedures, including:

• Lumbar & cervical facet joint radiofrequency denervation
• Sacroiliac joint pain management
• Chronic knee osteoarthritis pain treatment
• Peripheral nerve ablation under ultrasound guidance
• Medial branch nerve lesioning

Designed to support precise lesion targeting and predictable clinical outcomes in interventional pain therapy.

This disposable RF cannula is designed to provide stable insertion, accurate positioning, and consistent thermal lesion performance during radiofrequency ablation procedures.

Its optimized structural design helps physicians achieve controlled access to target nerves while maintaining safety and procedural efficiency.

Reduces insertion resistance and improves trajectory control during ultrasound or fluoroscopy-guided placement.

Ensures energy is delivered only at the active tip, minimizing unintended tissue interaction.

Supports consistent lesion formation with predictable thermal performance.

Provides structural strength and durability during interventional procedures.

Eliminates cross-contamination risks and supports infection control protocols.

Our RF cannulas are designed to be compatible with widely used radiofrequency ablation systems, including:
